Thomson Reuters Launches Certified Implementer Program for Accounting and Consulting Firms

Grant Thornton LLP designated the first Certified Implementer of ONESOURCE corporate tax solutions

NEW YORK, June 2, 2010 - Grant Thornton LLP - the U.S. member firm of Grant Thornton International
Ltd, one of the six global audit, tax and advisory organizations - is the
first firm to be named Certified Implementer of Thomson Reuters ONESOURCE(R)
corporate tax solutions, offered by the Tax & Accounting business of Thomson
Reuters. Grant Thornton's agreement with Thomson Reuters provides that any
Grant Thornton International member firm is eligible to participate in the
Certified Implementer Program (CIP).

CIP signifies a commitment by Thomson Reuters to deliver the highest
quality training and ongoing technical support to the leading accounting and
consulting firms, and was created to ensure the successful implementation and
integration of Thomson Reuters software solutions into corporate tax and
accounting departments. The program also provides a framework to foster
ongoing and consistent collaboration, essential to delivering total solutions
to corporate clients.

"Our clients, and indeed the market, recognize the unique skills Grant
Thornton brings to tax, accounting and risk management," said Mark Stutman,
Grant Thornton's national managing partner of Tax services. "Becoming
Certified Implementers of Thomson Reuters products demonstrates our
commitment to helping corporate tax departments optimize their operations. We
are pleased to take our relationship with Thomson Reuters to the next level
as we continue to provide leading services to our clients."

Grant Thornton will initially be certified to implement two Thomson
Reuters' products: ONESOURCE Tax Provision - a leading tax provision solution
with more than 24,000 users at 900 corporations in more than 100 countries;
and ONESOURCE WorkFlow Manager, which has 19,000 tax and accounting users
worldwide utilizing nearly 200,000 unique workflow processes.

"In response to the increased complexity of global reporting, corporate
tax and accounting solutions have become equally more sophisticated," said
Brian Peccarelli, president of Workflow & Service Solutions for Tax &
Accounting. "The CIP designation lets corporate tax departments know their
accounting and consulting firms fully understand Thomson Reuters products,
and as a result, will receive superior service surrounding the implementation
of our software. We are excited Grant Thornton has taken this step with us,
and expanding its relationship with Thomson Reuters as the first CIP member."

The CIP allows accounting firms to expand their practices related to the
ONESOURCE offerings, while providing multinational corporations with the
assurance these firms have been trained to provide unparalleled services for
these market-leading products.
